Oh yes electrolytes definitely! I'm still debating with myself about medicated or non medicated feed since I'd really like them to have an organic, soy and corn free diet. I've been researching chickens for almost a year now, I live at my dad's house( he lives in another area) so I basically did a lot of research prior to asking him for permission to have chickens so I could answer any questions he might have. Currently, I'm finalizing plans for the coop so we can get started on that.I know! I wanted to get chicks as soon as I saw the ones my friend had, but I made myself wait until I knew how to care for them and how to build the coop ect. I picked mine up, so I don't know how the feeling of getting them mailed! I know all of them not making it is unusual. If you are getting them through the mail, I would strongly suggest putting elctrolytes in their water!
